Script Creation Utility for Maniac Mansion (SCUMM) is a scripting language developed at LucasArts (known at the time as Lucasfilm Games) to ease development of the graphical adventure game Maniac Mansion, but since developed to be used as an engine for several more LucasArts adventure games.It falls somewhere between a game engine and a programming language, allowing designers to create locations, items and dialogue sequences without writing code in the language in which the game source code ends up.
